(FR) PROCEDE DE PURIFICATION DE L'ACETONE
Abstract:
(EN) A process is described for purifying acetone from a crude acetone-phenol mixture produced upon oxidizing cumene. In the process, an alkaline agent and an oxidizing agent are both added to the mixture to help remove aldehyde contaminants upon purification.
(FR) L'invention concerne un procédé de purification de l'acétone à partir d'un mélange phénol/acétone brut produit par oxydation de cumène. Dans ce procédé, un agent alcalin et un agent oxydant sont tout deux ajoutés au mélange pour aider à retirer les contaminants aldéhydes par purification.
